Despite low intra-cellular requirements for Ca in the higher plants, Ca deficiency has been recorded in agricultural and horticultural plants during recent years. Because of insufficient selective and active uptake of Ca and its slow translocation, a high Ca concentration at the root surfaces is essential. The Ca requirement also increases when the supply of other nutrients, particularly cations increases. The use of inorganic fertilizers containing Ca should therefore receive more consideration. 56 references. (Abstract retrieved from CAB Abstracts by CABI’s permission
